First, Window Clipboard History uses a buffer (virtual memory, i.e. pagefile.sys). If that buffer fills, it could be causing the issue. Images may be many megabytes, so are particular;y pernicious. To increase its size, do the following as Administrator.
- Press WindowsPause to open the System CPL.
- Select Advanced system settings for the System Properties dialog.
- Select the Advanced tab. [A bit redundant, n'est-ce pas?]
- Select Performance to view Performance Options.
- Select Advanced tab. [Yep, again.]
- Select Virtual memory to Change the page file size.
- Depending on available RAM and disk space, consider increasing the size. BTW, setting a Custom size, with Initial size and Maximum size set to the same value, prevents continual resizing of the page file, and concomitant disk fragmentation.
Second, there might be flaws in Microsoft's implementation of Windows History. You can turn it off, and try an alternative such as CopyQ or one of the other many clipboard managers. As with any software, check it at VirusTotal for possible malware.
And here's a workaround, though not an answer:
Add a system sound for the Windows SnapShot command, to confirm that screen shot was taken. You can do so using the tenforums.com .reg file, or follow these directions.
- Press Win, type
reg and select Regedit.
- Navigate to
HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default\ (or copy and paste that into the Regedit location bar).
- Add a key for
- Add the key
.Current to `SnapShot. Note leading end-stop (period).
- Add the key
.Default to `SnapShot. Note leading end-stop (period).
Now you can either put the location of the sound file in the
(Default) REG_SZ value, or use the Windows System Sounds control panel to select the sound for SnapShot.
Every time you press Prtsc or AltPrtsc (and Fn, if needed), you should hear a confirmatory sound.
Why MS did not include that key is a puzzle...
