Na Blocksolute už to není (bylo to 10 let staré), ale pro zajímavost (ne jako návod!) jak to kdysi s slmgr /rearm fungovalo:
Reset Windows 7 Rearm count and run indefinitely without crack
Rearm extends your Windows 7 activation and runs a countdown of 30 days. In this period, you need to activate it (which is generally cracked). Well, you can reset your Rearm count and run Windows 7 forever without cracking it actually. The process is not very complicated but requires little patience.
Many users may have left stranded after last Windows 7 update WAT – KB971033 for fighting against cracks and illegal activations. But using this trick by MDL Forum, you will be able to reset rearm count to infinity and use Windows 7 original forever without crack and downloading all Windows updated calmly.
Now let’s start: First, open Start and in the search field type services. On the opening of new window, find “Software Protection“, Right click on it and Stop.

Now Let’s go to C:\Windows\ServiceProfiles\NetworkService\AppData\ Roaming\Microsoft\SoftwareProtectionPlatform Right click file tokens.dat, We select Cut and paste it to your Desktop.
After doing this too, Go to C: Windows\System32. At this point we look for two hidden files, which by extension will have. C7483456-A289-439d-8115-601632D005A0. Once found, move them to your desktop. If you can not view them, you set the Show Hidden Files from Folder Options.
Now we return to the first step, in which I asked you to open Services After searching Start it. At this point keep the window open and in the meantime start the Command Prompt as Administrator and enter the command slmgr / dlv. Now back to the screen that you left open, head back to Software Protection and Start.

But now let’s concentrate on the three files that we pasted on the desktop. Replace them in their original positions, overwrite token.dat in C:\Windows\ServiceProfiles\NetworkService\AppData\ Roaming\Microsoft\SoftwareProtectionPlatform
the other 2 are placed in C:\WindowsSystem32.
Now, we are performing another important step of entering product keys for rearming. Open the Command Prompt as administrator like we always did. Run “slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX” replacing X marks with your default product key. Keys are as follows:
Ultimate – D4F6K-QK3RD-TMVMJ-BBMRX-3MBMV
Professional – HYF8J-CVRMY-CM74G-RPHKF-PW487
Home Premium – RHPQ2-RMFJH-74XYM-BH4JX-XM76F
Home Basic – YGFVB-QTFXQ-3H233-PTWTJ-YRYRV
Starter – 7Q28W-FT9PC-CMMYT-WHMY2-89M6G

The most important part was done, we can now reboot the pc. After turning on your computer, you can check whether the command was executed, then open the command prompt and type slmgr / dlv to check if the meter is actually restarted.
